CROSS REFERENCE TO RELATED APPLICATION

This application claims priority under 35 U.S.C. §119(e) to U.S. provisional Application No. 60/903,848, filed on Feb. 28, 2007, the entire content of which is incorporated herein by reference.

BACKGROUND

Typical oral pouch products include a paper or fabric pouch material enclosing tobacco or other food grade materials. The enclosed tobacco or other material provides flavor as the user sucks or manipulates the pouch, saliva mixes with the enclosed materials, and the flavors leach out of the pouch through pores.

Generally, the paper or fabric pouch does not have good flavor or mouth feel and is unsatisfying until saliva and juices from the enclosed material are released.

In addition, many pouch products have a moisture content that causes the product to require preservatives and/or refrigeration in order to maintain freshness. Refrigeration can be inconvenient and the use of preservatives is unattractive to many consumers.

Thus, there remains a need in the art for an oral product having a fabric or paper pouch that provides immediate oral gratification, and a low moisture content to prevent the need for refrigeration or the use of preservatives.

SUMMARY

Provided is an oral pouch product with a single layer, flavored wrapper. In a preferred embodiment, the oral pouch product includes a fibrous, flavored wrapper for enclosing an inner material. Preferably, the inner filling material includes a fibrous non-tobacco, plant material that is enclosed in the pouch. Once the flavor of the product has been consumed, the fibrous flavored wrapper is removed from the mouth and discarded.

Preferably, the fibrous flavored wrapper is made of a paper and/or fabric. Preferably, the fibrous flavored wrapper is non-disintegrable and/or non-dissolvable. Also preferably, the fibrous flavored wrapper allows the flavors of the inner filling material to leach out into the user's mouth as the user sucks and manipulates the oral pouch product.

In an embodiment, the paper and/or fabric is heat sealable so that once a portion of the inner filling material is placed on a first portion of the fibrous flavored wrapper, a second portion of the fibrous flavored wrapper can be positioned over the first portion of the flavored wrapper. The first portion and the second portion can be part of a single layer of fibrous material (e.g., the first and second layers can be part of a strip of paper of fabric or separate strips of such material). A seal, such as a heat seal or ultrasonic weld, is then formed between the two portions of flavored wrapper around the inner filling material. In another embodiment, the portions of flavored paper and/or fabric are adhered via adhesive or otherwise affixed together to form seams.

In a preferred embodiment, the fibrous flavored wrapper includes flavorants embedded therein that provide initial flavor to the user before the inner filling material mixes with saliva to release the flavors and juices from the inner filling material.

Preferably, the flavorants are applied to the fibrous pouch wrapper by spraying, coating, immersing, embossing, and/or dispersing. In an embodiment, the flavorants are added to the fibrous flavored wrapper in the form of spray dried flavors, essential oils, encapsulated flavors, coacervated flavors, suspensions, and/or solutions.

Preferably, when the flavorants applied to the fibrous pouch wrapper are encapsulated (e.g., microencapsulated beads), the flavorants also include controlled release mechanisms such as pH change, heat activation, or mechanical activation through manipulating or sucking. In addition, encapsulated flavorants can have coatings of various thicknesses so that the flavorants are released at varying rates to provide continuous flavor throughout use of the oral product.

In a preferred embodiment, the fibrous flavored wrapper also includes a browning inhibitor that inhibits discoloration of the flavored wrapper caused by the inner filling material prior to use. In another embodiment, food grade colorants can be added to the fibrous flavored wrapper to make a colored wrapper, apply patterns thereto, or identify the flavor of the inner filling material and flavored wrapper.

Also preferably, the fibrous flavored wrapper includes a softening agent so as to soften the fibrous flavored wrapper and provide a more comfortable mouth feel to the user. In an embodiment, the softening agent is selected from the group consisting of humectants, flavored oils, and combinations thereof.

In a preferred embodiment, the inner filling material includes fibrous, non-tobacco, plant material, which includes tea, spices, herbs, vegetables, food fibers, fruit and/or tea and botanical extracts. Preferably, the moisture content of the plant material is below about 15% by weight so as to avoid the need for preservatives and/or refrigeration.

DETAILED DESCRIPTION

As described herein, an oral pouch product includes a single layer, fibrous flavored wrapper that forms a pouch. Preferably, the pouch is filled with an inner filling material including a fibrous non-tobacco, plant material.

In a preferred embodiment, as illustrated in FIG. 1, the oral pouch product 10 includes a fibrous flavored wrapper 12. The fibrous flavored wrapper 12 is formed into a pouch that contains an inner filling material and is sealed.

Preferably, the pouch product 10 has a rectangular or elliptical shape. Other preferred shapes for the pouch product 10 include any shape selected from the group consisting of polygons, squares, rectangles, circles, ovals, heart, star, half-moon, crescent, leaf shapes, and combinations thereof.

In a preferred embodiment, the oral pouch product is sized and configured to fit inside the mouth, between a user's cheek and gum. Preferably, a rectangular shaped oral pouch product 10 is about 20 mm to about 35 mm long, about 10 mm to about 20 mm wide and about 3 mm to about 6 mm thick. In a preferred embodiment, the elliptical shaped oral pouch product, as illustrated in FIG. 5, has a major axis of about 20 mm to about 35 mm and a minor axis of about 10 mm to about 25 mm. Preferably, the elliptical shaped oral pouch product is about 3 mm to about 6 mm thick. The ellipse may be truncated along one or both axes. In a preferred embodiment, the oral product 10 weighs about 200 mg to about 600 mg per pouch regardless of the shape of the pouch product.

The fibrous pouch wrapper 12 may be a fabric and/or paper such as filter paper, papers used to construct tea bags, coffee filters, and the like. Preferably, the fibrous pouch material 12 is of the type suitable for contact with food, such as materials used for packaging and/or handling foods. Also preferably, the pouch material 12 is porous so that flavors and saliva can travel in and out of the pouch product 10 when in use.

In a preferred embodiment, the fibrous pouch wrapper 12 is heat sealable. Preferably, the inner filling material 16 is placed between a first layer 30 and a second layer 32, as seen in FIG. 2, of the fibrous pouch wrapper 12. A seal 14 is formed between the two layers 30, 32 around the inner filling material to form the pouch product 10.

As illustrated in FIG. 1, the flavorants 18 are applied to the fibrous pouch wrapper 12 to provide immediate release of flavor once the oral flavor product 10 is placed in the user's mouth. Preferably, less than about 1 mg or up to about 100 mg of a flavorant 18 is added to the fibrous pouch material 12. Most preferably, the amount of flavor added to the pouch is less than about 1% or up to about 5% by weight of the pouch contents. The amount of flavorant added can depend on the potency of the flavorant being added.

Suitable flavorants 18 include any flavorants commonly used in foods, confections, or other oral products. Exemplary flavorants include, but are not limited to, berry flavors such as pomegranate, acai, raspberry, blueberry, strawberry, boysenberry, and/or cranberry. Other suitable flavorants include, without limitation, any natural or synthetic flavor or aroma, such as menthol, peppermint, spearmint, wintergreen, bourbon, scotch, whiskey, cognac, hydrangea, lavender, chocolate, licorice, citrus and other fruit flavors, such as apple, peach, pear, cherry, plum, orange, lime, grape, and grapefruit, gamma octalactone, vanillin, ethyl vanillin, breath freshener flavors, butter, rum, coconut, almond, pecan, walnut, hazelnut, french vanilla, macadamia, sugar cane, maple, cassis, caramel, banana, malt, espresso, kahlua, white chocolate, spice flavors such as cinnamon, clove, cilantro, basil, oregano, garlic, mustard, nutmeg, rosemary, thyme, tarragon, dill, sage, anise, and fennel, methyl salicylate, linalool, jasmine, coffee, olive oil, sesame oil, sunflower oil, bergamot oil, geranium oil, lemon oil, ginger oil, balsamic vinegar, rice wine vinegar, and red wine vinegar.

Preferably, the flavorants are applied to the fibrous flavored wrapper by spraying, coating, immersing, embossing, and/or dispersing. In an embodiment, the flavorants are added to the fibrous pouch in the form of spray dried flavors, essential oils, encapsulated flavors, coacervated flavors, suspensions, and/or solutions.

In a preferred embodiment, when the flavorants are encapsulated, the flavorants also include controlled release mechanisms such as pH change, heat activation, or mechanical activation through manipulating or sucking. In addition, encapsulated flavorants can have coatings of various thicknesses so that the flavorants are released at varying rates to provide continuous flavor throughout use of the oral product.

When the flavorants are applied as suspensions or solutions, the inner material is dried after application of the flavorants to a moisture content of less than about 15% by weight of the inner material (e.g. less than about 14%, less than about 13%, less than about 12%, less than about 11%, less than about 10%, less than about 9%, less than about 8%, less than about 7%, less than about 6%, less than about 5%, less than about 4%, less than about 3%, less than about 2%, less than about 1%). Preferably, drying is avoided when volatile flavorants with vapor pressures close to or below that of the solvent, of the solution, are used so that the flavorants are maintained in the pouch material 12.

Most preferably, the amount of flavorant applied to the pouch is such that drying is unnecessary because the inner material is not wetted by the flavorant. In an embodiment, the flavorant is applied to the fibrous pouch material prior to the insertion of the inner filling material to prevent wetting of the inner filling material.

Also preferably, the pouch contains fibrous plant material with a controlled moisture content so that its water activity (aw) is preferably below 0.65, but at least below 0.7 aw or a level determined sufficient to prevent mold growth, this value typically ranging between 0.6 aw and 0.7 aw.

In a preferred embodiment, the flavorants or other functional additives are applied to the fibrous pouch wrapper without increasing the moisture content of the pouch and pouch filler. Additional moisture renders the product unstable against microbial growth by increasing its water activity to a point where mold or bacteria can grow, resulting in a short life or the requirement the product contain preservatives or be refrigerated. Thus, it is preferred that the water activity level of the product is such that the product does not require preservatives or refrigeration to maintain freshness.

In a preferred embodiment, the fibrous pouch material 12 also includes a softening agent 20. Preferably, the softening agent 20 makes the pouch material 12 soft and pliable to provide better comfort to the user upon insertion in the mouth.

Suitable softening agents 20 include humectants, oils, and the like. Humectants include, without limitation, glycerin and propylene glycol. Oils include any flavored and/or natural oils such as, without limitation, olive oil, sesame oil, peanut oil, coconut oil, corn oil, grapeseed oil, walnut oil, safflower oil, soybean oil, and/or sunflower oil. In addition, oils that have been flavored with herbs may also be used as a softening agent 20. Preferably, the softening agent 20 is a pleasantly flavored oil that provides an additional layer of flavor to the user and/or acts as the flavorant. The softening agent 20 may be applied to the pouch material 12 by spraying, coating, immersing, embossing, or any other technique.

Often, pouch products turn beige or brown over time due to the enclosed material. Therefore, it is also preferable to treat the pouch material 12 with a browning inhibitor 22 such as that used to prevent fruits from turning brown. Preferred browning inhibitors 22 include, but are not limited to, antioxidants, vitamin E, vitamin C, calcium chloride, sodium hexametaphosphate, sodium bisulfite, and combinations thereof. The browning inhibitor 22 may be applied to the pouch material 12 by spraying, coating, immersing, embossing, or any other technique.

In a preferred embodiment, coloring agents 24 are included in the fibrous pouch material 12. One or more coloring agents 24 may change the color of the pouch to create designs, patterns, a trademark, or to signify pouch flavor. (i.e. purple to signify grape flavor) The coloring agent 24 may be used to dye the pouch material 12 or coloring agents 24 can be printed onto the pouch material 12.

In a preferred embodiment, as illustrated in FIG. 2, the oral pouch product includes an inner material 16 enclosed within the fibrous pouch material 12. Preferably, the inner material 16 includes non-tobacco, botanicals and/or non-tobacco botanical extracts.

As used herein, the term “botanical” includes anything derived from plants including, but not limited to, extracts, leaves, fibers, stems, roots, seeds, flowers, fruits, pollen, and the like.

As seen in FIG. 3, the pouch product 10 can be in a half-moon shape and can include a single sheet of pouch material 12 folded over to create a first layer and a second layer with the inner material between the layers. A single seal 14 can seal the inner material within the pouch 10.

As illustrated in FIG. 4, the pouch product 10 can be a circular pouch. The first layer and second layer can be separate pieces of pouch material. 12 with the inner material placed therebetween. A single seal 14 circumscribes the enclosed inner material.

As illustrated in FIG. 5, the pouch product 10 is an elliptical shaped pouch. The pouch is made of a fibrous material 12. Seals 14 around the perimeter of the pouch hold the inner material within. The pouch material 12 includes flavorants 18, softening agents 20, browning inhibitors, 22 and/or coloring agents 24.

The examples provided below are exemplary and are not meant to limit any aspects of the embodiments disclosed herein.

Example 1

About 4 mg of flavorant was added to a paper pouch wrapper weighing about 20 mg. About 450 mg of an inner material was placed inside the pouch. The pouch was sealed to hold the inner material within the pouch.

Example 2

About 50 mg of canola oil was sprayed onto a paper pouch using an atomizer. The pouch weighed about 300 mg.

Example 3

A solution of propylene glycol and 3 mg of flavorant was formed. The solution was added to a pouch material weighing about 20 mg. An inner material weighing about 450 mg was placed in the pouch. The pouch was sealed to retain the inner material within the pouch.

The pouch of Example 1 showed rapid release of flavor from the product upon initial placement in the mouth. The pouch of Example 2 was noticeably softer than the pouch of Example 1 due to the inclusion of the softening agent. The pouch of Example 3 used propylene glycol, a softening agent, and flavorants so as to provide better flavor and a softer pouch.
